This adds support for syncing ownership on Unixes and on Windows. The
scanner always picks up ownership information, but it is not applied
unless the new folder option "Sync Ownership" is set.
Ownership data is stored in a new FileInfo field called "platform data". This
is intended to hold further platform-specific data in the future
(specifically, extended attributes), which is why the whole design is a
bit overkill for just ownership.
* lib/model: Override scan config for auto-accepted encrypted folders.
Encrypted folders should not have the fs watcher enabled and rarely
benefit from a scheduled rescan. The GUI adjusts the suggested
settings (watcher disabled, one day rescan interval) when accepting a
receive-encrypted folder. Mirror that behavior to the auto-accept
case where the GUI is not involved.
Versioning also does not work well for encrypted folders, same
treatment.
An off-by-one error could cause tokens to be forgotten. Suppose
tokens := []string{"foo", "bar", "baz", "quux"}
i := 2
token := tokens[i] // token == "baz"
Then, after
copy(tokens[1:], tokens[:i+1])
tokens[0] = token
we have
tokens == []string{"baz", "foo", "bar", "baz"}
The short test actually relied on this bug.
This commit replaces `os.MkdirTemp` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `os.MkdirTemp`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

Showing all folders from disconnected or paused remote devices as
unaccepted would be a lot of false positives. As we cannot know
whether the remote has accepted while it doesn't have an active
connection, let's better report false negatives, as in assuming the
folders are accepted.
* lib/api: Note ItemStarted and ItemFinished for default filtering.
The reasoning why LocalChangeDetected and RemoteChangeDetected events
are not included in the event stream by default (without explicit
filter mask requested) also holds for the ItemStarted and ItemFinished
events. They should be excluded as well when we start to break the
API compatibility for some reason.
* gui: Enumerate unused event types in the eventService.
Define constants for the unused event types as well, for completeness'
sake. They are intentionally not handled in the GUI currently.
* cmd/syncthing: Harmonize uppercase CLI argument placeholders.
Use ALL-UPPERCASE and connecting dashes to distinguish argument
placeholders from literal argument options (e.g. "cpu" or "heap" for
profiling). The dash makes it clear which words form a single
argument and where a new argument starts.
This style is already used for the "syncthing cli debug file" command.
* lib/model: Simplify event data structure.
Using map[string]interface{} is not necessary when all values are
known to be strings.
Having a separate mutex for the three or four instructions needed to
fetch and increment nextID means the overhead exceeds the cost of this
operation. nextID is now handled inside the critical section for
awaiting instead, while the more expensive channel creation has been
moved outside it.
This is mostly a simplification, though it may have minor performance
benefits in some situations. The single-threaded sender benchmark shows
no significant difference:
